IMPROVEMENT IN CANDLE-MOLD TIPS.

Specification forming part of Letters Patent No. 138,380, dated April29, 1873; application filed March 29, 1873.

To all whom it may concern:

lyn, in the county of Kings and State of New York, have invented a newand useful Improvement in Candle-Molds; and I do hereby declare thefollowing to be a full, clear, and exact description thereof, referencebeing had to the accompanying drawing forming a part of thisspecification, in which Figure 1 is a sectional view of the lower end ofa candle-mold fitted with my improved plug or mandrel. Fig. 2 is adetached view of the ln I Like letters of reference indicate like partsin each.

My invention consists in an improvement in the manner of packing themovable bottoms of candle-molds to prevent the exudation of wax aroundthe sides of the same.

. To enable others skilled in the art to make and use my invention, Iwill describe its con struction and mode of operation.

The mold a has its bore or opening 0/ extended clear through from end toend, and is closed at its lower end by the inserted plug or mandrel b.The inside, 0, of the mandrel b is cone-shaped for forming thecandle-tip, and the mandrel is tapped or perforated, as at d, so as toallow the candle-wick to pass through it into the mold. The parts areall old and well known in the construction of candle-machines.

Heretofore various ways of packing the de- ,vice or part which forms thebottom of the mold (which, in this case, is the mandrel b) have beenpractised, but with varying success. It has been exceedingly diflicultto prevent a slight film of the heated wax from entering between thesides of the movable bottom and the mold, which when it sets causes thebottom to stick, and thereby materially retards or affects the operationof the machine- One of the ways practiced is to place a packing-ringupon the flange e'of the removable cap f of the mold, and to have acorresponding shoulder on the movable bottom, which seats upon thepacked flange.

To overcome this difliculty, I make a groove, g, around the plug ormandrel b and fill it with any suitable packing so as to close the endof the mold sufficiently to prevent the exudation of the wax frombetween the mold and the plug, but not so tight as to prevent themovement of the plug when starting or popping the candle. The plug b isdesigned, as before said, to start or pop the candle from the mold, sothat it may be drawn out by the wick or butt end, which then protrudesfrom the top of the mold. When the wax which forms the candle becomesset it adheres to the sides of the mold, and the candle requires to bestarted so as to free it from the mold. This is the function of themovable plug 1). The movement of the plug for this purpose is butslight, being at most only about one and one-quarter inches. Thismovement is communicated to the plug in various ways well known to thoseskilled in the art.

What I claim as my invention, and desire to secure by Letters Patent,is-

The groove gin the side of the plug or movable bottom b, adjacent to thesides of the the mold a, for the reception of packing, substantially asand for the purposes described.

In testimony whereof I, the said ISAAC COLE, have hereunto set my hand.
